50 mbs enough for google maps voice turn by turn directions

When I got my Koodo phone there was a 50mb data plan included. At that time I had no need for data so they put a block on data. Now, I would like to use the google maps turn by turn directions. Is 50 mb enough to do what I want to do ?

Check out Mapfactor Navigator or HERE if you have decent storage on your phone. The maps are downloaded when you install the app (via wifi, of course!) Count on 2 GB of data for all of North America.

Now, when you are on the road, the only time you will need data is when you do a search for a location or address. Rest of the time you can turn-by-turn with data off, since the maps are already on board.
